Damper (Manual / Actuated)

DAMPER MANUAL & ACTUATED

are essential components of HVAC and air distribution systems, designed to regulate, control, and balance the movement of air within ducts and ventilation networks. Manual dampers are adjusted by hand to control air volume, while actuated dampers use electric or pneumatic actuators for automatic or remote operation. Manufactured using GI (Galvanized Iron) or aluminium, these dampers provide reliable performance, durability, and efficient air control in commercial, industrial, and institutional applications.
